So, the vocals are very good and the mid-range sound is delicate\u003cbr\u003e- The resistors of the circuit are 718 resistors. Japanese Omron is used for protection circuit. Driver is NJE15034\/35 for ON\u003cbr\u003e- 6 pairs of 2SC5200 transistors, 1943, or 4 pairs of Sanken transistors can be used as power transistors. Transistors for ON can also be used\u003cbr\u003e- A60 circuit module with current feedback. The main feature of the circuit is the use of complementary push-pull circuit from the input stage to the output pole. This makes it easy to achieve a slew rate of hundreds of volts per microsecond, which is quite good for capacitive loads\u003cbr\u003e- Japanese Omron+ UPC1237 protection circuit ensures that the output is safe and reliable, protecting your speakers\u003cbr\u003e- Japanese 50A Sanken bridge rectifier\u003cbr\u003e- Midpoint servo circuit for more stable output.
